Q: Color of Fruit Fly Medium

[d17oug18]

OK! Im having this wierd problem with my FF food lately, after the breeding and a few days pass, this redish color flows through the top of the food? It doesnt stop them from eating or breeding but i just want to know if mold or something harmful can be red? or is like... blood? idk ??? Any help would be great, thanks.

PS

ill post pics in the comments if more information is needed.

It's possible that they're red mites.

It is a mold, won't hurt them.
